To all coir/om ii concern it known that l, lira-ran S'mwrln'r, a citizen oi rho United States, residing county of Roanoke and Stare a, have invented certain new and ovemenis in Brake-Linings, of which the following is a specification lily invenlion relates to an improvement in linings of brake or transmission bands, especially of the iypc now commonly used with the Ford automobile.

' A great deal. dii'iicullv is experienced uhen these linings become Worn, for the reason that the; are KlVClEfl fast i0 lhe brulco or transmission bands. llhis is overcome by the'prcscnl. invention in the provision of a removable inner band, which carries the brake-lining, which is adapted r0 be slid enrlwise and held at its ends against. the brake or transmission band end lugs.

My invention consists in a brake-lining band to which the bralroliniug is riveted or olherwisc secured, and slidably and detach abl v connccled with the brake or transmission band, with i'rs ends constructed and adapted to receive the clutch or brake pedal shaft that regularly extends through the brake or lransmissionband end lugs, for applying and releasing friction upon the drum.

In the accompanying drawings:-

Figure 1 is a view in perspective of the ordinary Ford type of brake or transmission band, with my improved lining applied;

Fig, 2 is anenlargecl transverse crosssection; and

Figs. 3 and l are transverse sectional per it s ective views, the Iormer showing a grooved term, and the, latter showing rivets for guiding she inner band into place.

The numeral :1 represents the usual brake or transmission band, to which ordinarily the bralre lining; is riveted, but without any brake-liningn In my invention, 'lhis brake or transmission band has a channel 2 formed substantially throughout its length, preferably in the transverse center thereof, and formed by bonding is bodily into the band, although it might be formed otherwise.

At the ends of the band 1, ihcrc are the usual upsiuuding open slotted lugs riveted thereon, although this, of course, constitul'es no part or" my present invention.

The numeral 3 is the inner flexible band, which has the brake-lining i riveted or othwhen turned, apply or release friction as is (ii-wise secured .thereto. This inner band 3 may be bent to form a ridge 5 adapted to loll'on lhc channel 2 of the outer brake or transmission band 1 in throwing the lining into place within the brake or transmission band. in lieu of this, the heads of the rivers 8, which secure the brake-lining t0 the inner band 3 might be fashioned to follow this channel :2, as shown in Fig. 4.

My invention also contemplates making the outer surface of the inner band 3 preferably smooth. it may not be necessary to guide lhe inner band laterally in taking its place as a lining: of'the outer brake or transmission band, as the pressure is notonly always endwise ihcreon, but also the lining is necessarily put in place by pushing endwisc, although it is perfectly obvious that some means of guiding it in place, such as the channel and rib, or channel and rivetheads, or their equivalents, would %:perhaps in some instances facilitate and quicken the operation of assembling these parts.

The ends of the inner band. 3, which car ries ihe iiralre'lining, may be doubled over, as at 2', and provided with either an. open or closed slot 8, or might have a slotted plate rivaled or otherwise attached, which end in any instance is adapied to lie flat against or be beat up against the regular end lugs in position to receive the screw roclcshaft or shafts to which the clutch, brake, and reverse pedals are secured, which,

Well understood.

To insure holding the ends 7 in place against the hugs, the bendable side clips 9 may be provided, these preferably being made to embrace the lugs and hold the ends and lugs in tight embrace.

Obviously oi'her more or less slight changes might be made besides those recounted herein, the essential feature bein to provide an easily rep]aceablobrake-ban lining, which perhaps could be applied to any other brake of the band type, such as used in other makes of automobiles as well as in the Ford. and hence I do not mean by anything herein to limit myself strictly to the exact forms and arrangements set forth.

I claim; ,I
